Photometric Calibrator Instruction Manual, 01124, Rev. J2
4 SETUP MODE
This section describes the setup variables which are used to configure the analyzer.
4.1 Setup Mode Operation
All the setup variables are stored in the analyzer's EEPROM and are retained during power off
and even when new software revisions are installed.
NOTE
If a variable is modified, but ENTR is not pressed, the variable will
not be changed and the analyzer will beep when EXIT is pressed.
4.2 Setting Automatic Multipoint (ASEQ) Check
Automatic sequence of multipoint calibration can be programmed to select one zero and five
span points 20%, 40%, 60%, 80%, and 100% of selected (see Section 3.4 How to set
concentration) O
3
concentration by pressing sequence of SETUP-EVNT-ASEQ-AZ5S.
Likewise, select AZS for zero and one span point (selected O
3
concentration), select AS2S for
zero and two span points 25% and 100% of selected O
3
concentration, or press OFF to disable
pre-programmed automatic sequence. If ASEQ is selected, then front panel's yellow status LED
will be turned on.
4.3 Setting Automatic Zero/Span Duration
Duration of each zero/span calibration step can be programmed by selecting SETUP-EVNT-
WAIT. Enter the duration between 1 - 20 minutes for the zero check and then press ENTR.
similarly enter the duration for span check and press ENTR.
NOTE
Teledyne API recommends that the durations are set at least 10
minutes to allow for an accurate and reliable ZERO or SPAN value
to be established.
Automatic zero/span calibration will be initiated once per day on a timed basis. Set starting time
of the automatic calibration by selecting SETUP-EVNT-TIME. Time should be between 00:00
- 23:59.
Starting time of the automatic cal. can be shifted ± 60 min to avoid missing data of remote
analyzer during same time of the day. Set desired shift time by selecting SETUP-ENVT-SHFT.
